I have a Hisense TV. I was wondering if there’s an easy way to firewall their TV so that it only has access to Google Store and Netflix? Make it so the TV can’t reach anything else?
I don’t currently have any firewall. I have ddwrt as my main router. I can whip up a pihole if needed.
Limit what domains it can lookup, force it through proxy that is whitelisted to only the domains you want it to access, and block all outbound traffic for it to the internet. It won’t be perfect.
I did something similar. Took a few hours to review squid/bind logs to find what was needed.
